Apple is looking for a low-level programmer that specializes in vector optimization and numerics. More specifically, the company wants someone familiar with ARM architecture and its NEON vector processing unit. As MacRumors explains, NEON is used specifically to refer to the vector unit in ARMv7 Cortex processors, while current iPhone and iPod touch hardware use ARMv6-based processors. The obvious conclusion is that future hardware will be based on the Cortex architecture, which is also capable of multi-core variants—and a multi-core processor opens up an avenue for improved background processing capabilities.

Furthermore, the ideal candidate for the embedded video processing engineer position would have experience with real-time streaming over WiFi and cellular networks. The mention of cellular networks in particular suggests the job is connected to the much-rumored video capabilities in iPhone OS 3.0. Clearly, future hardware will be optimized to enhance such capabilities.

Both job listings are for unfilled positions, so it's not likely this work will affect new hardware expected to be announced at WWDC in a few weeks. However, hints of multiple iPhone and iPod touch devices, as well as at least one unknown device, were found in betas of iPhone OS 3.0. It's clear that multimedia will play an important role in whatever Apple has up its sleeve.
